Dean Designs YouTube Banner

I made this banner for myself and I have no clue how i made it look this decent. I think the brush in photoshop is amazing for blending the sky or background of the image or banner, the lighting on all 3 merged images were inconsistent so i brushed with a soft brush on top to make it look natural and merged. I really enjoyed making it and I am glad it looks good. Check out My YouTube If you guys can, I post speed art of banners and I will post tutorials of how to do stuff like that. I am an up and coming graphic designer and I am still learning stuff on how to make different style banners and I would like to learn how to make logos as well.
